"Cross-platform" gets used loosely, so here's the honest version: a genuinely cross-device game either runs natively everywhere or lives in a browser, and it doesn't ask your friend group to all own the same hardware before you can play together. Here are ten that actually deliver on that.
1. Chess.com
Runs as a full site in any browser and as native apps on phones and tablets, with your account, rating, and games-in-progress synced across all of them. About as close to universal as gaming gets.
2. Minecraft
Bedrock Edition supports crossplay across PC, mobile, and consoles, with the same world and account following you between devices.
3. Fortnite
Full crossplay across PC, mobile, and consoles has been standard for years -- squad up regardless of what everyone's holding.
4. Among Us
Lightweight enough to run on nearly anything, with crossplay between PC and mobile built in from early on.
5. Brawl Stars
Primarily mobile but playable through emulation and increasingly native cross-device support, with a huge active player base to match into.
6. Rocket League Sideswipe / Rocket League
The mobile spinoff and the original both support online play across the devices they're available on, sharing the core game's crossplay-friendly design.
7. Call of Duty: Warzone Mobile
Built specifically to bring the Warzone experience to phones with crossplay ambitions toward the wider Call of Duty ecosystem.
8. Marvel Snap
A fast, session-based card game built mobile-first but fully playable on PC too, with progress tied to your account rather than a device.
9. Stumble Guys
A lightweight, low-barrier party battle royale that runs comfortably across phones, tablets, and PC without needing serious hardware on any of them.
10. Any browser-based multiplayer game
This category deserves its own entry because it sidesteps the whole cross-platform question entirely -- a browser game doesn't care what device opened the tab. There's no app store, no separate mobile build, no "which version do you have." If it can open a browser, it can play.
The pattern worth noticing
Every entry above either lives in a browser or was deliberately engineered for crossplay by a large studio -- it's genuinely hard to build. Most games aren't cross-platform, and plenty that claim to be still restrict play to within the same store or ecosystem. Browser games are the one category where "works on any device" isn't a feature that had to be built -- it's just what a browser tab already is.
That's the entire premise behind RivalPit: 110+ casual multiplayer games -- notebook classics, board games, original arcade titles -- that open in a browser tab on a phone, a Chromebook, a ten-year-old laptop, or a brand-new Mac, and just work, every time, for everyone in the group at once.
Frequently asked questions
What does "cross-platform" actually mean for a game?
It means the game runs on more than one type of device (phone, PC, console, etc.) and typically lets players on different devices play together in the same match, with progress and friends carrying over via a shared account.
Do cross-platform games require downloading on every device?
Most do — you still install a native app or client on each device, it's just the same account and progress following you. Browser-based games are the exception: there's nothing to install on any device, you just open a tab.
What's the easiest way to play with friends who all have different devices?
Pick a game or platform that's browser-based or has true crossplay built in — that way nobody needs to own a specific console or a powerful PC just to join in.
Are browser games as good as installed games?
For casual and multiplayer party-style games, yes — the format was never about graphical horsepower. For graphically demanding single-player AAA games, no, that's not what browser games are built for.
